we are thinking how are we going to be able to track the users that only "see" an experiment
meaning, a user lands on a page, gets allocated to 'B' but doesn't do anything else, how will growthbook know this user was part of the experiment?

it is up to you to track that event to your data warehouse using whatever event tracking system you like

(if you don't have any event tracking setup, we can recommend some)
